If you're planning on watching/watching Zankyou No Terror, this will spoil the ending for you in some ways. But if you're not planning on watching it, you might enjoy this as it is a pretty good ending.

"In an alternate version of the present, Tokyo has been stricken by a shocking terrorist attack, and the only hint to the identity of the culprit is a bizarre video uploaded to the internet. The police, baffled by this cryptic clue, are powerless to stop the paranoia spreading across the population.

While the world searches for a criminal mastermind to blame for this tragedy, two mysterious children—children who shouldn't even exist—masterfully carry out their heinous plan. Cursed to walk through this world with the names Nine and Twelve, the two combine to form "Sphinx," a clandestine entity determined to wake the people from their slumber—and pull the trigger on this world."

Zankyou no Terror was a good show, I'm not sure what to think about the ending. But as the whole show itself, I really liked it. Assuming you liked Zankyou no Terror, I'd recommend you to check out - Eden of the east. It's very similar if you ask me, and they also have terrorism as the theme around the plot.

Oh I not long finished watching this! I enjoyed the show. I liked the ending because it wasn't a typical fairytale ending, although I wouldn't call it my favourite.
